Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
【小題1】   Which of the following is true according to the passage？

A．Genetic limitation will be beneficial for some women
B．A large number of genes will prevent us from developing
C．Prohibition(禁止) of cloning might limit the freedom of scientists

【小題2】What’s the author’s opinion on cloning?
A．Cloning should be entirely banned
B．Cloning should be used in creating life
C．Cloning will take away the right to reproduce
D．Cloning is acceptable if it is used for cloning organs

It happened to me recently that I was telling someone how much I had enjoyed reading Barack Obama’s Dreams From My Father and how it had changed my views of the current US President. The person I was talking to agreed with me that it was, in his words, “a wonderfully written book.” However, he then proceeded to talk about Mr. Obama in a way that suggested he had no idea of his background at all. I sensed that I was talking to a book liar(說謊者)．
And it seems that he is not the only one. Clearly two thirds of people have lied about reading a book which they haven’t. In The World Book Day survey, Dreams From My Father is at number 9. The survey lists top ten books, and various authors, which people have lied about reading. As I’m not one to lie too often, I’ll admit here and now that I haven’t read the entire ten books. But I am pleased to say that I have read the book at number one, George Orwell’s 1984. I think it’s absolutely outstanding．
Asked why they lied, the most common reason was to impress someone they were speaking to. This could be difficult if the conversation became more in-depth!
The World Book Day survey also has some other interesting information in it. It shows that many people lie about having read classical works by Jane Austen, the Bronte sisters, Charles Dickens and so on. But when asked which authors they actually enjoy, they named JK Rowling, Jilly Cooper, and Stephen King. Forty-one percent of people asked admitted they turned to the back of the book to read the end before finishing the story．
So which books have you lied about reading —if any — and which is your favorite?
【小題1】The main reason why people lie about reading is to __________.         

A．make fun of the listenerB．impress the listener
C．please the listenerD．interest the listener
【小題2】The underlined word “proceeded” in the passage probably means“___________”.
A．wantedB．happenedC．continuedD．stopped
【小題3】What is the best title for the passage?
A．Are You A Book Liar?B．Readers Are All Liars
C．World Book DayD．Dreams From My Father

Dear Editor,
I’m a middle school student naming Lily. I’m writing to tell you something I don’t think it good. Recently I’ve noticed many of my classmates often went to the Internet bar near our school. The other day I went there, too. I was very surprising to see many students playing games, seeing films and chatting. Some were even talking about love affairs on-line. In my opinion, an Internet bar should be a place which we can find much useful information. As is known to all that the Internet is a window to an outside world rather than a place for games. The Internet is good if we make good use it. Otherwise, it will do us great harm. So the local government should take measure to make sure that the students use Internet bars positively.

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)，選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

It’s natural to greet friends with a smile and a wave. ____1._______ But what happens if your face and body send mixed messages? Would someone be more likely to believe the look on your face or the way you hold your body?

Scientists have recently tackled these questions. They found that when a person is looking at your face, she might not believe what she sees of your body language doesn’t? match the feeling that your face shows.? 2.? Previously, they had found that the tone of a person’s voice can be more important than the words that are spoken. For example, most people tend not to believe a person who says in a flat voice, “I’m so excited.”

???? When it came to emotions conveyed by facial expressions and body language, most scientists suspected that the face was more important. To test if this was true, psychologists from the Netherlands and Boston showed people a number of pictures of isolated faces and isolated bodies(with faces blurred out)that showed anger or fear. ___3._____

???? An angry face had low eyebrows and tight lips. A scared face had high eyebrow and a slightly open mouth. ____4._____? A scared body had arms forward and shoulders square, as if ready to defend.

???? These results told the researchers that mixed signals can confuse people. Even when people pay attention to the face, body language subtly influences which emotion they read.

? ?? 5.? And if you want to be understood, it helps to avoid sending mixed messages.

Studying such mixed messages is nothing new for scientists.

A. So, your body language is important for telling people how you feel.

B. Scientists feel new to study the mixed message that confuses people.

C. An angry body had arms back and shoulders at an angle, as if ready to fight.

D. Body language can sometimes be misunderstood in different culture backgrounds.

E. When you do this, your face and body work together to show your friends that you’re happy to see them.

F. They also showed pictures in which angry or scared faces were paired with angry or scared bodies.
